She’s used to sharing a stage with her four Saturdays bandmates but Una Healy looked calm and confident as she went solo for a gig at Bush Hall in West London last night.

Promoting her debut solo album The Waiting Game, Una showed off her vocal and guitar skills in a lacy black dress.

The singer's new acoustic sound may be a slight departure from her pop past but fans took to Twitter full of praise after the show.

One fan tweeted: " UnaHealy still on a high from last night it was amazing being back at bush hall for your own headline show this time, what a great night." Another added: "Tonight was amazing! The crowd was so chilled and everyone just had fun, left all their worries at the door UnaHealy."

The singer - who formed the group with Frankie Bridge, Mollie King, Vanessa White and Rochelle Humes nine years ago - explained that fans may have to wait until the 20th anniversary.

Speaking to the Daily Star, she said: "It’s usually when a band is celebrating 15 or 20 years, but it would be a while before we can get to that point. It will be more interesting then too, because of our solo careers."

She added: "I imagine when the time comes and nostalgia for us kicks in we will do those hits," she added.

"Hopefully, when we do reform we have the back catalogue to play along with new stuff.”

Aside from her solo career, Una is also a devoted mother to her daughter Aoife Belle, five, and son Tadhg, two, with husband Ben Foden.
